On the off chance the problem still exists then you may have a corrupted profile. I strongly suggest updating to the final version of Firefox 3.0 asap. Here’s a couple of suggestions that I’m sure will help.įirst and foremost, the problem with your HDD crunching away like that is most likely due to Firefox populating the anti-phishing SQLite database (urlclassifier3.sqlite) with updated information and in Firefox 3 RC1 there’s a major bug with that along with several others.
